摘　　要：δ铁素体析出行为控制是1Cr17Ni2马氏体不锈钢性能控制的关键,本文利用模拟软件JMatPro计算了C、Mn、Cr、Ni、N五元素对δ铁素体析出温度的影响,以寻求最佳元素搭配,达到避免δ铁素体在常用加热温度范围内析出,提高钢的强度和硬度。利用实验室热处理试验,揭示了加热温度对δ铁素体析出量的影响规律,为制定合理的加热温度制度提供了依据。Control of 5 ferrite precipitation behavior is the key of martensite stainless steel lCrl7Ni2.In order to find the best match of chemical element so as to avoidδferrite precipitating within the scope of usual heating temperature and so improve the steel strength and hardness,the effect of C,Mn,Cr,Ni,N onδferrite precipitation temperature was caculated by JMatPro software.Experiment was carried out on laboratory heat treatment experiment,the effect law of heat temperatur onδferrite precipitation behavior was revealed,the work provide a reference for heating temperature design of the steel.
